GEORGE ROBINS, OF JACKSON, MICHIGAN.

HORSESHOE HEEL-CALK.

Application filed March 27, 1915.

To all whom it may concern Be it known that I, Gnoncn RoBINs, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Horseshoe Heel- Calks, of which the following is a specification, reference being had to the accompanying drawings.

My present invention relates to new and useful improvements in horse shoes and has particular reference to an improved form of heel calk.

The principal object of the invention is to provide a heel calk of simple design, which is so constructed that it may be easily and quickly attached to or removed from the heel portion of a horse shoe, without requiring any material changes in the design and formation thereof.

The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the ac companying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form part of this application.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a plan view of the bottom face of a horse shoe equipped with my improved heel calk; Fig. 2 is a detail view in side elevation of the one heel of the shoe equipped with my improved calk; Fig. 3 is a detail perspective view of the calk; Fig. 4 is a detail perspective view of the heel of the shoe; Fig. 5 is a detail view in side elevation of a modified form of calk applied to a shoe heel; and Fig. 6 is a detail perspective view of this modified calk.

As best disclosed in detail in Fig. 1 of the accompanying drawings, the horse shoe designated by the numeral 10 is downwardly offset at its rear terminals, as indicated at 11. At the inner end of each offset portion 11 and on the side faces thereof, are formed the lateral stop shoulders 12 which are adapted to limit the sliding movement of the heel calk 13, when this member is being applied to the shoe.

The heel calk is formed as a single casting Specification of Letters Patent.

and includes a body portion 1 1, the upper end of which is provided with a U-shaped saddle 15, and the inner face of which is provided with the right-angularly extending attaching plate 16. The saddle is shaped to conform to the cross section of the portion 11 and is limited in its inward sliding movement thereon by the shoulders 12. The attaching plate 16 is curved, as shown in Fig. 2 to conform to the curvature of the under face of the heel portion of the shoe. A pairof openings 17 are formed in this plate to receive the bolts 18 which are threaded into the heel portion of the shoe and serve to hold the calk, in position thereon. The longitudinal edges of the plate are provided with the upstanding flanges or lips 19 which seat against the chamfered faces 20 of the shoe and serve to relieve the bolts of any transverse strain which may occur.

In Figs. 1, 2 and 3, I have illustrated the body portion of the heel call: as being tapering or wedge-shape. Obviouslv, however, the body of the call: may be formed as a rectangular block, as shown in the modified form of the device in Figs. 5 and 6.

In reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred to in the above description as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in the details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of this invention, as defined by the appended claims.

What is claimed is:-

1. The combination with a horse shoe, of a heel calk including a body portion, an attaching plate extending laterally from the inner side thereof. fastening members for securing the attaching plate to the shoe heel, and a saddle extending upwardly from the body portion of the calk and in vertical alinement therewith, said saddle being disposed to embrace the terminal of the shoe.

2. The combination with a horse shoe having a pair of vertical shoulders formed in its side faces adjacent the heel, of a heel calk including a body portion, an attaching plate extending laterally from the inner side thereof, bolts passing through the attaching plate and into the shoe, and a saddle extending upwardly from the body portion of the calk and embracing the terminal of the shoe, said saddle being engaged with the. shoulders when the calk is attached to the shoe.

3. The combination with a horse shoe having vertical shoulders formed on its side faces, adjacent its heel terminal, ofa calk including a body portion, a saddle'extending upwardly therefromto embracethe heel. of the shoe, said saddle being engagea ble against the shoulders, an attaching plate extend laterally from the body of the vcalk and bearing against the under face of the shoe, bolts passing through the attaching plate and into the shoe, and flanges formed on the longitudinal edges of the plate and seating against the shoe for, holding the plate against transverse movement thereon;

4. The combination with a horseshoe, of a calk including a body portion, a saddle rising from the body portion in vertical alinement therewith, said saddle being disposed to embrace the heel of. the shoe, an attaching plate extending laterally from the bodyof.

the calk and bearing against the under face of the shoe, the rear end of the shoe being downwardly offset and the top of the plate 7 being disposed above the surface of the upper en'dofthe body member and merging graduallyinto the same, whereby a rounded shoulder is formed at the junction of the plate and body to engage with the downwardly'ofl set portion'of the shoe heel. s 5.=;The combinat ion with a horse shoe, of a calk including a body portion, a' saddle rising therefrom to embrace the heel of the shoe, an attaching plate extending laterally from. the, body of the :c alk and bearing against the under face ofithe shoe, fastening members for securing the, plaiteutog the shoe heel, and inwardly directedflanges. formed on the longitudinaledges of. the. plate, said flanges sea-ting against the longitudinal edges of the heel portion of.- the shoe for holdingthe plate against transverse movementthereons i In testimony-whereof I hereunto ,afiix my signature in the presence of two witnesses.
